Scalia was noted for holding a conservative approach to the law.[4] He also believed in originalism. This means he wanted the Constitution interpreted exactly as its framers had wanted it. Scalia and fellow judge Clarence Thomas often had the same viewpoints. He was friends with justice Ruth Bader Ginsburg.

On March 16, 2016, President Obama nominated Merrick Garland to replace Scalia.[5] After Republicans refused to give Garland a confirmation hearing, his nomination expired in January 2017. On January 31, 2017, President Donald Trump nominated Judge Neil Gorsuch to replace Scalia.[6] Gorsuch was sworn into office on Monday, April 10, 2017, in two ceremonies.[7]
